Question
Select the set in which the numbers are related in the
same way as are the numbers of the following set. (NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits. E.g., 89 - Operations on 89 such as adding/ subtracting/ multiplying etc. to 89 can be performed. Breaking down 89 into 8 and 9 and then performing mathematical operations on 8 and 9 is not allowed) (9, 3, 144) (11, 4, 225)Solution
The logic followed here is: 3rd number = (1st number + 2nd number)² (9, 3, 144) → (9 + 3)² = 12² = 144. (11, 4, 225) → (11 + 4)² = 15² = 225. (24, 2, 576) → (24 + 2)² = 26² = 676. (18, 4, 320) → (18 + 4)² = 22² = 484. (28, 2, 900) → (28 + 2)² = 30² = 900. (15, 6, 400) → (15 + 6)² = 21² = 441.
